It is just unimaginable that a Hollywood beauty had actually contributed to science. Hedy Lamarr was a heart-throb to millions of people. She was successful Hollywood actress. But she was an inventor as well and this was her invention, rather than her beauty, which guaranteed she would never be forgotten. Her invention for frequency-hopping spread-spectrum was used to jamming the signals of enemy’s torpedoes. In fact, her invention was instrumental in modern technologies such as Bluetooth, CDMA and Wifi.
